  • Protocol summary

    The aim of this study was to investigate the effects of acute magnesium IV loading on improving dyspnea in patients with acute COPD exacerbation referred to the emergency department of Imam Reza hospital during February and July 2015. In this randomised double-blind placebo-controlled trial study, 72 patients with exacerbated COPD undergo baseline peak-flow-metry and are subsequently randomized to 2 groups in a double-blind design. All patients receive routine treatment of COPD exacerbation and patients in the case group receive 2 grams of intravenous magnesium sulfate in 100cc normal saline, patients in control group receive 100cc normal saline. Peak-flow-metry is performed 15, 30, and 45 minutes after administration of magnesium sulfate or placebo and patient are asked about severity of dyspnea based on the 5 point likert scale. Primary outcomes are subjective improvement of dyspnea, improvement of peak-flow-metry measurements, tracheal intubation in the period of admission and length of stay in the emergency department. Inclusion criteria was any patient older than 18 years old with acute exacerbation of COPD and exclusion criteria were any other underlying causes for dyspnea including heart failure, asthma, renal failure, pneumothorax, pneumonia …

    هدف از اين مطالعه تعیین تاثیر منیزیم سولفات وریدی بر بهبود حمله تنگی نفس در بیماران مراجعه کننده با حمله حادCOPD به اورژانس بيمارستان امام رضا (ع) در طي مدت 6 ماه (از بهمن ماه93 تا آبان ماه 94) است. در اين مطالعه تصادفي، دوسويه كور، تك مركزي، 40 بیمار دچار حمله حاد COPD به صورت تصادفی به دو گروه منیزیوم سولفات وریدی و دارونما تقسیم می شوند. برای هر دوگروه درمان روتینCOPD انجام می شود. برای گروه مداخله 2گرم منیزیم سولفات وریدی در 100 سی سی نرمال سالین در عرض 20 دقیقه انفوزیون وریدی می شود و برای گروه دارونما به جای آن 100 سی سی نرمال سالین انفوزیون می شود. از همه بیماران قبل از دریافت منیزیم یا دارو نما و 20 دقیقه بعد از دریافت منیزیم یا دارو نما،پیک فلومتری انجام می شود و میزان تنگی نفس بیماران بر اساس مقیاس لیکرت 5 تایی چک می شود. پيامدهاي اوليه مورد بررسي در بیماران عبارتند از بهبود سابجكتيو تنگي نفس در بيماران و بهبود پيك فلومتري و نیاز به انتوباسیون و مدت زمان بستری. معیار ورود به مطالعه هر بیمار بالای 18 سال مبتلا به COPDاست و معیار خروج از مطالعه وجود هر گونه علت زمینه ای برای تنگی نفس بیماران از جمله نارسایی قلبی، نارسایی کلیوی، پنوموتوراکس، پنومونی، آسم و .. است.

    The study was conducted at the emergency department of Imam Reza hospital, Mashhad. Iran. 80 Patients with acute exacerbation of COPD were randomly allocated to one of the two groups (MgSO4 or placebo) and received routine treatment. MgSO4 groups were given intravenous infusion of 2.5 g of MgSO4 (5 ml of 50% solution) in 50 mL of 0.9% normal saline and placebo group were given or 5 ml sterile water in 50 mL of 0.9% normal saline (placebo group). PEFR and Dyspnea severity score (using 10 point Likert scale) recorded after the first nebulization and 30 minutes after commencement of the last nebulization (90 minutes after ED presentation)

    در اين مطالعه كه در بخش اورژانس بيمارستان امام رضا (ع) مشهد انجام شده است، 80 بیمار دچار حمله حاد COPD به صورت تصادفی به دو گروه منیزیوم سولفات وریدی و دارونما تقسیم می شوند. برای هر دوگروه درمان روتینCOPD انجام می شود. برای گروه مداخله2.5 گرم منیزیم سولفات وریدی در 50 سی سی نرمال سالین در عرض 20 دقیقه انفوزیون وریدی می شود و برای گروه دارونما به جای آن 5 سي سي آب مقطر در 50 سی سی نرمال سالین انفوزیون می شود. PEFR و شدت تنگی نفس (بر حسب لیکرت ۱۰ تایی) در ابتدا بعد از اولین دوز بتاآگونیست استنشاقی و در پایان پروتکل درمانی (۹۰ دقیقه بعد از ورود به اورژانس) اندازه گیری و ثبت می شد.

    Because of some limitation in Conducting the study such as (but not limited to) not being able to buy a nebulizer and peak-flow meter on time, the study did not conduct at the arranged time. Tow years later that we started to perform the study and enroll the patient, we did some amendment was proposed by the methodologist which needs to be updated here.

    به دليل محدوديتها در تهيه نبولايزر و پيك فلومتر و يك سري مشكلات اجرايي ديگر، تحقيق در آن زمان مقرر انجام نشد و در زمان حدود دو سال بعد كه نمونه گيري شروع شد با مشاوره با متخصص آمار يك سري اصلاحات اعمال گرديد كه به روز رساني ميشود.

    We performed block randomization with a block size of 4 using a computer generated random sequence. This was administered by a third party process so that patients and researchers were unaware of allocation and randomly allocated patients to one of the two groups of the study. The MgSO4 group received vial A. The placebo group received vial B.

    روش تصادفی سازی: تصادفی سازی بلوکی با استفاده از بلوکهای ۴ تایی که با استفاده از یک سکانس رندوم با کامپیوتر ایجاد شده بود واحد تصادفی سازی: فردی این کار توسط شخص سوم (مشاور آمار) انجام پذیرفت و مجریان و بیماران از نحوه اختصاص بیماران مطلع نبودند. هرروز دارو یا دارونما توسط پرستار مسوول شیفت آن روز در سرنگ های ۵ سی سی مشابه تهیه میشد و تحت عنوان A یا B لیبل گذاری میشد و در اختیار مجریان قرار میگرفت

    Daily, the chief nurse who was not involved in the patients’ care blindly provided the MgSO4/placebo by filling similar vials, labeled A or B, with 5 mL MgSO4 (50% solution) or 5 mL sterile water. The MgSO4 group received vial A. The placebo group received vial B.

    هر روز سرپرستار اورژانس در آن شيفت كه دخالتي در مطالعه نداشت، سرنگ هاي 5 سي سي از آب مقطر يا منيزيوم سولفات 50% را تهيه ميكرد و به عنوان داروي A (منيزيوم سولفات) يا B (آب مقطر) در اختيار محققان بيمار قرار ميداد. پزشك مسوول بيمار (مراقب باليني و ارزيابي كننده فرايند ) و محقق و بيماران (شركت كنندگان) نسبت به دارويي كه تجويز ميشد بي اطلاع بودند.

Protocol summary

Study aim
To investigate the clinical benefits of IV MgSO4 as an adjuvant to standard treatment in patients with Acute exacerbation of COPD (AECOPD)
Design
Double blind randomized clinical trial with parallel groups in phase 3, with 41 cases in each group
Settings and conduct
The study was conducted at the emergency department of Imam Reza hospital, Mashhad. Iran. 80 Patients with acute exacerbation of COPD were randomly allocated to one of the two groups (MgSO4 or placebo) and received routine treatment. MgSO4 groups were given intravenous infusion of 2.5 g of MgSO4 (5 ml of 50% solution) in 50 mL of 0.9% normal saline and placebo group were given or 5 ml sterile water in 50 mL of 0.9% normal saline (placebo group). PEFR and Dyspnea severity score (using 10 point Likert scale) recorded after the first nebulization and 30 minutes after commencement of the last nebulization (90 minutes after ED presentation)
Participants/Inclusion and exclusion criteria
Enrollment: All adult patients with AECOPD who gave consent to participate and their PEFR was < 50% 20 minutes after the first dose of beta agonist. Excluded: need immediate endotracheal intubation or mechanical ventilation, hemodynamically unstable, uncooperative to perform peak flow meter, pregnant, other conditions contributing to dyspnea, such as pneumonia, pleural or pericardial effusion, pneumothorax, heart failure, renal failure, or any other serious medical conditions.
Intervention groups
group A (MgSO4 group) who received IV infusion of 2.5 g of MgSO4 in 50 mL of normal saline group B (placebo group) received 5 ml sterile water in 50 mL of normal saline
Main outcome variables
Primary outcomes: PEFR percent predicted and Dyspnea Severity Score at the end of treatment protocol (90 minutes after ED presentation). Secondary outcome: change in RR, SpO2, need for endotracheal intubation or noninvasive ventilation and ED discharge rate

General information

Reason for update
Because of some limitation in Conducting the study such as (but not limited to) not being able to buy a nebulizer and peak-flow meter on time, the study did not conduct at the arranged time. Tow years later that we started to perform the study and enroll the patient, we did some amendment was proposed by the methodologist which needs to be updated here.

Randomization (investigator's opinion)
Randomized
Randomization description
We performed block randomization with a block size of 4 using a computer generated random sequence. This was administered by a third party process so that patients and researchers were unaware of allocation and randomly allocated patients to one of the two groups of the study. The MgSO4 group received vial A. The placebo group received vial B.
Blinding (investigator's opinion)
Double blinded
Blinding description
Daily, the chief nurse who was not involved in the patients’ care blindly provided the MgSO4/placebo by filling similar vials, labeled A or B, with 5 mL MgSO4 (50% solution) or 5 mL sterile water. The MgSO4 group received vial A. The placebo group received vial B.
